Abstract
We observe that excited hadrons provide an opportunity to probe from experiment the power-law running of the quark mass in the mid infrared, while the condition m(k)<k remains valid. A relatively clean analysis is possible for the maximum spin excitations of the Delta baryons, analogous to the yrast states in nuclei. Such states are accessible at current experimental facilities such as ELSA and Jlab.
